django redis配置和简单使用

配置

# 设置redis缓存
CACHES = {
    # 默认缓存
    "default": {
        "BACKEND": "django_redis.cache.RedisCache",
        # 项目上线时,需要调整这里的路径
        "LOCATION": "redis://127.0.0.1:6379/0",

        "OPTIONS": {
            "CLIENT_CLASS": "django_redis.client.DefaultClient",
        }
    },
    # 提供给xadmin或者admin的session存储
    "session": {
        "BACKEND": "django_redis.cache.RedisCache",
        "LOCATION": "redis://127.0.0.1:6379/1",
        "OPTIONS": {
            "CLIENT_CLASS": "django_redis.client.DefaultClient",
        }
    },
    # 提供存储短信验证码
    "sms_code": {
        "BACKEND": "django_redis.cache.RedisCache",
        "LOCATION": "redis://127.0.0.1:6379/2",
        "OPTIONS": {
            "CLIENT_CLASS": "django_redis.client.DefaultClient",
        }
    }
}

# 设置xadmin用户登录时,登录信息session保存到redis
SESSION_ENGINE = "django.contrib.sessions.backends.cache"
SESSION_CACHE_ALIAS = "session"

使用

# 获取redis连接
red = get_redis_connection('sms_code')

code = '%6d' % random.randint(1, 999999)
red.setex('phone_%s' % phone, 5 * 60, code, )
red.setex('phone_%s_interval' % phone, 60, code)

redis事务操作

code = '%6d' % random.randint(1, 999999)
# 使用事务来操作命令，一条失败全都是失败
# 创建管道
pipe = red.pipeline()
# 开启事务
pipe.multi()
pipe.setex('phone_%s' % phone, SMS_EXPIRATION_TIME, code, )
pipe.setex('phone_%s_interval' % phone, SMS_INTERVAL_TIME, code)
# 执行事务
pipe.execute()
